Definitions

the present invention relates to agricultural balers, and, more particularly, to a tail gate arrangement for a round baler.
Agricultural harvesting machines such as balers, are used to consolidate and package crop material so as to facilitate the storage and handling of the crop material for later use.
a mower-conditioner is typically used to cut and condition the crop material for windrow drying in the sun.
an agricultural combine discharges non-grain crop material from the rear of the combine defining the straw (such as wheat or oat straw) which is to be picked up by the baler.
the cut crop material is typically raked and dried, and a baler, such as a round baler or large square baler, straddles the windrows and travels along the windrows to pick up the crop material and form it into bales.
a round baler may include a main bale chamber where the crop material is rolled into a bale of a predetermined size, and then typically wrapped with twine or mesh.
the main bale chamber is typically configured as an expandable chamber, with a plurality of carrier elements positioned around at least a portion of the periphery of the bale chamber.
the carrier elements can be in the form of rollers, chains and slats and/or belts.
the rear of the baler is configured to open and allow the bale to be discharged from the rear of the baler, and the discharge operation accounts for down time of the baler and thereby reduces the overall efficiency of the baler.
some type of tail gate at the rear of the baler opens to allow the bale to be discharged.
DE 102 50 425 discloses an agricultural baler which has additional swiveling arms for a protective sheet to cover the baling chamber of the baler when a bale is being formed in the baling chamber.
This sheet is held by crossbeams and rollers at the top and bottom of the machine. Although the sheet covers the baling chamber during normal operation, such a construction might not be strong enough in the event that something goes wrong and the not yet completed bale is trying to escape from the baling chamber.
the present invention provides a two part tail gate with an upper tail gate arrangement which pivots at it's top, front, and a lower tail gate arrangement which pivots at an approximate center of the bale chamber. Configured in this manner, the lower tail gate arrangement quickly ejects the bale from the bale chamber.
the invention in one form is directed to an agricultural baler, including a frame, a tail gate arrangement carried by the frame and arranged in an arcuate arrangement around a bale chamber.
the tail gate arrangement includes an upper tail gate arrangement and a lower tail gate arrangement.
the upper tail gate arrangement has a first pivot axis located at an upper, forward portion thereof.
the lower tail gate arrangement has a second pivot axis located at an approximate center of the bale chamber when viewed in cross section.
the agricultural baler is characterized in that it includes an electrical processing circuit which is configured for carrying out a bale discharge operation using the upper tail gate arrangement and the lower tail gate arrangement, based on the following discharge sequence: 1) sensing a full bale condition within the bale chamber, corresponding to a predetermined size of the bale; 2) opening the upper tail gate arrangement by pivoting the upper tail gate arrangement about the first pivot axis to an open position; and 3) ejecting the bale by pivoting the lower tail gate arrangement about the second pivot axis to an eject position.
the ejecting step can further begin when the opening step is partially completed.
the discharge sequence can further include the step of wrapping the bale with a wrapping material, after the sensing step and prior to the opening step.
An advantage of the present invention is that the bale is quickly ejected from the bale chamber.
Another advantage is that the overall efficiency of the baler is increased by reducing the down time associated with bale ejection from the baler.
the baler 10 is towed by a prime mover, such as a tractor 14.
the baler 10 can also be a self-propelled baler for certain applications.
Crop material is lifted from windrows into the baler 10 using a pickup unit 16.
the pickup unit 16 includes a rotating pickup roll 18 with tines 20 which move the crop rearward toward a bale chamber 22.
the crop material is rolled into a bale of a predetermined size within the bale chamber 22, and then discharged through the tail gate arrangement 12 to the field where it is subsequently picked up for transport.
the bale chamber 22 is configured as an expandable bale chamber with a plurality of carrier elements 24 carried by a frame 26.
the carrier elements 24 are arranged in an arcuate arrangement around the bale chamber 22, and function to engage and roll the expanding hay bale as the crop material is fed into the bale chamber 22.
the plurality of carrier elements 24 are configured as a plurality of rollers.
the carrier elements can be variously formed, such as rollers, chains and slats, and/or belts.
the plurality of carrier elements 24 include an upper tail gate arrangement 12A and a lower tail gate arrangement 12B.
the upper tail gate arrangement 12A includes a plurality of the carrier elements (i.e., rollers), and has a first pivot axis 28 located at an upper, forward portion thereof.
the first pivot axis 28 is located at the axis of rotation of the upper, forward roller 24'. With the first pivot axis 28 at this location, the upper tail gate arrangement 12A opens in a clam shell type manner.
the lower tail gate arrangement 12B also includes a plurality of the carrier elements (i.e., rollers) and has a second pivot axis 30 located at an approximate center of the bale chamber 22, when viewed in cross section.
the lower tail gate arrangement 12B can pivot between a closed position (shown in Fig. 1A ), and an open position (shown in Fig. 1B ) allowing the bale to exit from the tail gate 12 (counter-clockwise as shown in Fig. 1A ). With a pivot location 30 as shown, the lower tail gate arrangement 12B can pivot very fast (compared to known tail gate arrangements), thereby decreasing the discharge cycle time and improving the overall efficiency of the baler 10.
the agricultural baler 10 can further include an electrical processing circuit 32 which is configured for carrying out a bale discharge operation using the upper tail gate arrangement 12A and the lower tail gate arrangement 12B.
the electrical processing circuit 32 can carry out the bale discharge operation, based on the following discharge sequence:
the electrical processing circuit 32 is coupled with suitable actuators (not shown), which are in turn coupled with the upper tail gate arrangement 12A and the lower tail gate arrangement 12B, for pivoting the upper tail gate arrangement 12A and the lower tail gate arrangement 12B about the respective pivot axes 28 and 30.
the step of ejecting the bale by pivoting the lower tail gate arrangement 12B about the second pivot axis 30 to an eject position may start before the step of opening the upper tail gate arrangement 12A is completed.
the lower tail gate arrangement 12B may start to open, such that the fully open position of the upper tail gate arrangement 12A and the fully open position of the lower tail gate arrangement 12B is reached simultaneously or almost simultaneously.
a sensor (not shown), connected to the electrical processing circuit 32, may be used to detect when the upper tail gate arrangement 12A has reached the position on which the lower tail gate arrangement 12B may start to move, such that collision between the upper tail gate arrangement 12A and the lower tail gate arrangement 12B is prevented.
the signal from the sensor for detecting the position of the upper tail gate arrangement 12A is thus used by the electrical processing circuit 32 as an input signal and taken into account during the execution of the discharge sequence.
the discharge sequence can further include the step of wrapping the bale with a wrapping material, after the full bale condition is sensed and prior to opening the upper tail gate arrangement 12A.
the upper tail gate arrangement 12A can be opened when the wrapping step is partially completed.
the upper tail gate arrangement 12A can be opened when the bale has been wrapped with at least one full revolution of wrapping material (e.g., mesh or twine).
Fig. 2 shows an embodiment of a baler 40 which is similar to the baler 10 shown in Fig. 1 .
the primary difference is that the carrier elements 24 forming the upper tail gate arrangement 12A and the lower tail gate arrangement 12B are configured as chains and slats, rather than rollers.
the upper tail gate arrangement 12A still has a first pivot axis 28 located at an upper, forward portion thereof, and the lower tail gate arrangement 12B still has a second pivot axis 30 located at an approximate center of the bale chamber 22, when viewed in cross section.
